IEEE80211_CHAN_NO_HT40PLUS and IEEE80211_CHAN_NO_HT40PLUS channel
flags tell if HT40 operation is allowed on a channel or not.
This patch ensures ht_capability information is modified
accordingly so that we don't end up creating a HT40 connection
when it's not allowed for current regulatory domain.

1.8.1.4
From: Xinming Hu <[email protected]>
Host hang is observed if card is removed before firmware download
gets completed. In this case, firmware will be failed to download and
adapter structure gets freed.
In other thread, mwifiex_remove_card() waits on semaphore until the
firmware download fails. This wait is not necessary and may result in
invalid adapter access.
This patch uses down_trylock to return immediately so that hang issue
won't occur.
